Sara needs to take a taxi to get to the movies. The taxi charges $6 for the first mile, and then $2.75 for each mile after that . If the total charge is $14.25, then how far was Sara's taxi ride to the movie ?

Answers

Answer:

The total miles it took to go to the movies is 4 miles (counting the first mile that cost $6)

Step-by-step explanation:

Variables:

x = per mile

y = total

Equation:

y = 6 + 2.75x

Given:

y = 14.25

Work:

y = 6 + 2.75x

14.25 = 6 + 2.75x

2.75x = 14.25 - 6

2.75x = 8.25

x = 8.25/2.75

x = 3

Answer:

So the first step is to subtract $6 from 14.25.  

We get 8.25.

divide 8.25 by 2.75, to find out how many miles (after the 1st mile) Sarah's ride was.  

8.25/2.75 = 3.  So 3 + 1 = 4.  

The total mileage length to get to the movies was 4 miles.

The price of an item has been reduced by $9.94. The original price was $62.45. What is the price now?

Answers

Answer: The price now is $52.51

Step-by-step explanation: To find the price after a reduction, we need to subtract the amount of the reduction from the original price. In this case, we have:

Original price = $62.45

Reduction = $9.94

Price after reduction = Original price - Reduction Price after reduction = $62.45 - $9.94

Price after reduction = $52.51

We can also check our answer by adding the reduction to the price after reduction and seeing if we get back the original price:

Price after reduction + Reduction = Original price $52.51 + $9.94 = Original price $62.45 = Original price

This confirms that our answer is correct.

Hope this helps, and have a great day! =)

The distance, d, you bike varies directly with the amount of time, t, you bike. Suppose you bike 31.125 miles in 2.5 hours. Write an equation that relates d and t.

Answers

Answer:

d=10.8t

Step-by-step explanation:

The distance "d" you bike varies directly with the amount of time "t" you bike.

Therefore d a t

To turn it into a equality , we introduce k, proportionality constant

d=kt

The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,

d α t

To turn it into equality, we introduce k, proportionality constant.

d = kt

We find the value of k from the given conditions. Suppose you bike 31.125 miles in 2.5 hours.

31.125 = k(2.5)

k = 12.45 miles/hour

Therefore the equation would be:

d = 12.45t

Step-by-step explanation:

   x₂,y₂

B(1,6)

m = (y₂ - y₁) / (x₂ - x₁)

m = (6 - 4) / (1 - (-5))

m = 2 / (1 + 5)

m = 2/6

m = 1/3

y = mx + b              B(1,6)

6 = (1) * 1/3   + b

6 = 1/3  + b

b = 6 - 1/3

b = 17 / 3

y = x/3 + 17/3

Answer:

The way that Earths axis is tilted is what determines the season that it is. for example when the Northern hemisphere tilts toward the Sun, it's summer in the Northern Hemisphere. And when the Southern hemisphere tilts toward the Sun, it's winter in the Northern Hemisphere. This is because when a hemisphere is tilted towards the sun, that hemisphere is getting direct rays from the sun.
